Multi-element intermediate alloy for impure copper refining, preparation thereof and application thereof

Abstract

The invention belongs to the technical field of non-ferrous metal material processing, and particularly relates to a multi-element intermediate alloy for impure copper refining, preparation thereof and application thereof. A Cu-P-La-B multi-element intermediate alloy is adopted, and strengthened refining is carried out on impure copper in a smelting process and a casting process, so that good deoxidation and deslagging effects are achieved; the quality of a copper bar product produced by the alloy is equivalent to that of a copper bar which is produced by taking cathode copper as a raw material; and moreover, operations are simple and convenient, and cost is relatively low. According to the multi-element intermediate alloy, the preparation thereof and the application thereof, equivalent or value-added recycling of the impure copper can be expected to be realized, and the application prospect is wide.

Description

technical field

[0001] The invention belongs to the technical field of nonferrous metal material processing, and in particular relates to a multi-element master alloy for refining red copper and its preparation and application. Background technique

[0002] my country's copper resources are scarce, and the recycling of scrap copper has become an important measure to make up for the shortage of copper resources. However, in the process of direct remelting and regeneration of waste miscellaneous copper, if the treatment continues, the quality of recycled products will be significantly reduced. It is an important part of my country's copper processing industry to use copper materials such as waste wires, cables, bus bars and other copper materials with relatively simple components to directly remelt to prepare copper materials for electrical, electric power, and electronics. At present, for the remelting and refining of red miscellaneous copper in the industry, phosphorus (P) ...
